O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him. 123 When a chapter (of the Quran) is revealed, some people ask others, "Whose faith among you people has received strength from this (revelation)?" It (the revelation) certainly strengthens the faith of the believers and they consider it to be a glad news. 124 And as for those in whose hearts is a disease, unto them it hath increased pollution to their pollution, and they die while they are infidels. 125 Do they not see how once or twice every year they are tried? Yet still they neither repent nor remember. 126 Whenever a chapter is sent down, they glance at each other, (asking): 'Does anyone see you' Then they turn away. Allah has turned away their hearts, for they are a nation who do not understand. 127 Assuredly there hath come unto you an apostle from amongst yourselves: heavy upon him is that which harasseth you, solicitous for you, and with the believers tender and merciful. 128 But if those [who are bent on denying the truth] turn away, say: "God is enough for me! There is no deity save Him. In Him have I placed my trust, for He is the Sustainer, in awesome almightiness enthroned." 129
